Specication of Letters Patent.

Patented July 2, 1907.

Application filed September 21, 1906. Serial No. 335,602.

To all 'whom t may concern:

Be it known that I, HENRY CLAY LYON, a citizen of the United States, and a resident of Howard Lake, in

and to deliver them singly at the ball of the hammer,

and hold them in such position in line with the hammer head that they may be partially driven into an 4object by a blow oi the hammer without being handied. l

Such objects I accomplish by the means illustrated in the accompanying drawings, in which drawings like characters oi' reference indicate like parts throughout the views, and in which Figure l is a side elevation partly broken away of a hammer embodying my invention; Fig. 2 is an end elevation of the same broken away on the line 2-2 oi Fig. l.; Fig. 3 is a central longitudinal section, partly broken away, oi the parts shown in Fig. l; Fig. 4 is a central longitudinal section o the parts shown in Fig. 3, showing some of the elements differently disposed; Fig. 5 is a horizontal section taken on the line 5--5 of Fig. 2; and Fig. 6 is a horizontal section taken on the line 6-6 o Fig. 3. I f

As illustrated in the drawings, a hammer head l is secured to a handle 2 by means of a transverse pin I. A hopper 3 is secured to the upper portion of the head, and opens into a curved passage 51 formed between curved guide plates 5. The lower ends of the guide plates 5 extend adjacent to a reciprocating shutter 6,

which is provided with an elongated slot 6a having enlarged slots 6b at each end thereof. Directly below the shutter 6 is a shelf 7 having its "upper edge extending in line with the curved passage formed by the plates 5. The shelf 7 is' arranged within a conical hopper 8 which is provided on its upper end with offset horizontal lips .8 extending outward from the sides of the hopper, as shown in Fig. 5. The lower portion of the hopper 8 is arranged inline with a sleeve 9, which is secured to the ball Ib of the hammer by means oi a pin 9L. Directly beneath the sleeve 9 is a reciprocating head or shuttle l() provided with a lower guide plate l0, a central portion 10b having spring jaws l0 secured thereto, and an upper guide pnt@ 10d.

The upper guide plate l0d is provided with a recess l0c having an open end, and the upper surface ot' the f guide plate 10l1 is beveled or inclined adjacent to said slot, as indicated at lOf in Fig. 6. A reciprocating bar l1 is mounted on the handle 2 and arranged with- .in a longitudinal slot 2a formed in the handle. The

bar 11 is provided with an arm 1l extending upwardly and engaging at its end a slot 6 formed in the shutter 6. An arm 11b is also connected with the bar 1l and is pivoted at its lower end to the sliding block 10 by means of a pivot pin 110. The forward end of the bar 11 is pivotally connected with a bent lever l2, which lever is pivdtally mounted upon the handle 2 by means of a pivot pin l2, A spring 13 bears at one end against the under side of the lever 12, and its opposite end is held i in position by means of a latch 3g secured to said lid.

:The bottom of the hopper is provided with a downwardlyA inclined plate 3c which bends upward at its edge 3d so as to aid in holding back the bulk of the Y' nails and allow them to pass singly through the opening 3e formed in the bottom of the hopper into the curved passage 5b formed by-the curved plates 5. A

- curved ledge 3JL is also preferably attached to the inner portion of the hopper, which also tends to hold back the bulk of the nails and prevents them from be- ,coming too closely. packed around the opening 3e. Such ledge also tends to keep the nails from bindingk together and enables them to lie in a horizontal position and thereby pass freely out of the hopper 3 and onto the inclined plates 5. A bent lever 4 is pivotally attached by means of a pin la to the hopper, and

. the outer arm or' said lever is provided with a weight 4b.

When the hammer is up-ended, as when working on ceiling laths, the weight 4b causes that arm of the le- The inclined plates 5 have diplates from the upper to the lower ends thereof, as shown in Fig. 2. As the nails descend on the plates vr5 their heads bear against the diverging edges 0i' the plates, and are drawn transversely oi the plates 5, so that when they reach the lower end of the passage 5b,

the heads oi the nails drop into the end slots 6b formed in the shutter 6, the body of the nails lying in the slot 6 opening into the end slots 6b. A slot 3b may be iormed in the side of the hopper, and a slot 5*L formed in one of the guide plates 5 so as to aid in removing any obstruction that might lodge between the guide plates. When a nail drops into the slot 6 of the shutter 6, the nail is supported on the shelf 7 which lies directly below the slot 6L o the shutter 6, as shown in Fig. 4.

The spring 13 which is mounted upon the handle 2 and bears against the under surface of the bent lever 12 holds the lower portion of said lever forward in its normal position, thereby drawing forward the bar 11 piv oted to the lower end of said lever and drawing backward the shutter 6 so as to hold the slot 6 in alinement with the lower portion of the passage 5b. By pressing on the lever 12 which is preferably provided with a thumb piece for that purpose, the lower arm of said lever is thrown backward carrying with it the bar 11 and the shutter 6 connected to the upper end of the arm 11 formed on said bar. Such backward movement of the shutter 6 carries the nail lying in the slot 6L of from the shelf 7, thereby permitting the nail to drop into the hopper 8. As the shutter 6 is pressed backward, the end slots 6b of the shutter extend over the lips 8*L which project outwardly horizontally from the upper portion of the hopper 8, as shown in Fig. 2. When the nail drops from the slot 6, therefore, the head of the nail strikes one of the lips 8 of the hopper which thereby retards the movement of that portion of the nail, and allows the body of the nail to drop vertically into the hopper 8, thereby up-ending the nail into a vertical position. As the nail passes through the opening of the hopper and the sleeve 9, it drops into the slot 10 formed in the upper guide plate 10d ofthe reciprocating block 10, the head of the nail resting on the beveled edge 10E of said plate, and the body of the nail is clamped by the spring jaws 10c which are secured to the central portion 10b of the block 10. When the nail is in such position and pressure is released from the lever 12 mounted on the handle, the tension of the spring 13 ldraws the bar 11 forward, carrying with it the block 10 supported in a recess 1C formed in the ball lb ofthe hammer, thereby bringing the nail in line with the ball of the hammer. The nail may then be partially driven into an object by a blow of the hammer. After the nail has been partially driven into such object, the hammer is drawn backwardly so as to release the spring arms 10c rom the body oi the nail, the open end of the slot 10O permitting the head o the nail to be withdrawn from the top plate 10d. The nail is then driven fully to place by the hammer. The end oi the bent lever 12 may then be pressed downwardly against the tension oi' the spring 13, so as to move backwardly the bar 11 and the shutter 6 connected therewith and thereby remove another nail trom the shelf 7 and permit it to drop out o the slot L of the shutter 6 into the hopper 7, and from said hopper into the jaws 10c of the sliding block 10, to be then drawn forward in the block 10 by means of the tension of the spring 13 so as to bring the nail in striking position in line with the ball ofthe hammer, as shown in Fig. 4.
